This assembly from Eagle is designed to handle the demands of racing, including setups that use nitrous or forced induction. It's a complete package that takes the guesswork out of matching critical internal engine components.

At the heart of this assembly is a forged 4340 steel crankshaft with a 4.150-inch stroke. Paired with it are 6.760-inch H-beam connecting rods, known for their strength and reliability under high stress. These rods use 7/16-inch ARP 8740 bolts, a popular choice for their durability. The pistons are forged 4032 aluminum flat tops, featuring an -8cc dish to help achieve your desired compression ratio, and come with plasma-moly file-fit rings for a good seal. To ensure smooth operation and longevity, the assembly includes King XP series rod and main bearings.

This rotating assembly comes balanced from the factory, saving you a significant step and cost in your engine build. It's important to note that this assembly is not CARB approved and cannot be shipped to California.
